Spinning off a little from this topic I think it would be interesting hearing what people consider an optimal working week would look like. Weighing different factor against each other, such as the total productivity against productivity rate against the end of a long working day, economic wealth against less working hours and quality of life etc. One may argue that as we have economic growth and productivity goes up we should take some of that to shorten the working hours leaving more time to spend with the children, family and friends. Others may argue that it's not worth slowing down the economy.
